BOSTON (AP)  Officials in Massachusetts say they’ll reveal the contents of a time capsule dating to 1795 and believed placed by Samuel Adams and other Revolutionary War luminaries early next month.

The state and the Museum of Fine Arts say the contents of the capsule unearthed at the Statehouse in Boston will be unveiled on Jan. 6.

The small capsule is believed to contain items such as old coins, documents, newspapers and a metal plate owned by Paul Revere. Officials believe some of the items likely deteriorated over time.

Originally made of cowhide, the capsule was believed to have been embedded in a cornerstone when construction on the state Capitol began in 1795. Adams was governor of Massachusetts at the time. The contents were shifted to a copper box in 1855.
